Check all the little lights, in the trunk, interior of the car, even under the hood sometimes, to see if one is stuck on. Find it's switch.

SOURCE: alternator light on

The alternator is not producing any power . If it were the engine would run without the battery. Check the wiring on the alternator. It must ave an exciter wire to make it work.

SOURCE: The battery is constantly being replaced because

i suggest you visit another dealership. ask for the "head tech" to look at your vehicle. if something on the car is draining the battery they should be able to pinpoint the problem. if you have any aftermarket electronics installed make sure they know what they are. also on the 430 if the doors are nto completely closed the light at the bottom of the door opening will stay on. you should not need to "turn the car on" every other day. thats nonsense. if you park in a garage try pulling into the garage shut the door and turn out the lights, if something is on in the car you may be able to see it.

SOURCE: BATTERY CONSTANTLY BEING DRAINED DOWN. VEHICLE

I am reluctant to pass this along as it is a simple means of troubleshooting. Hopefully you have a battery charger.

this will take several nights to finally isolate the
problem but here goes...

Each night remove a differnet fuse from your fuse box and re-install the fuse the next morning. The day your battery is no longer draining (good start in the morning) you have found the circuit causing the problem.

With 2 batteries and 4 alternators this almost sound like you have shorted wiring some where on the engine. It takes a 35 - 50 amp short to brun up an alternator so the short would have to be on a pretty good sized wire otherwise your car would have caught fire by now from a chassis harness shorting and causing the fire.

Just a thought... hopefully some idiot did not run the positive output lead of the alternator back to the negative battery terminal and no one has caught it. (Just a random thought but it really would take something thqat direct to burn up 4 alternators)

Personally.... Having gone through the expenses in attempted repairs that you have experienced, I would be seeing another shop. I know you said they were the sole agents.... that does not prevent you from visiting a shop that has a good auto electrician. I know it has to be frustrating.

These are the known issues with the A4:

Battery keeps drainging


Try disconnecting the alternator leads overnight but make sure they are kept away from the body, the big cable is always HOT. See if that does it overnight. If its OK then the alts duff. If not then get a small tester / amp meter set up and connect it between the neg post and the neg lead. This will give you some idea of the drain in amps. With the car locked as normal remove and replace the fuses to lights,door locks etc until the ammeter suddenly reads zero. Then you have an idea of which item is draining it. Door locks are an old favourite after the alternator. Alternators can back drain a batt even if they show a charge when running. Get a pal with electrical knowledge to help.

Why is battery light lit on dashboard constantly ford explorer 2004


Usually when the battery light is constantly on when running the alternator is not charging properly or the wire from the alternator to the battery is damaged. If your battery is good the car may run for quite some time if headlights and heavy drain accessories are not used. Suggest you have the system checked at a local chain auto parts store like Advance Auto who can tell you if your car alternator is charging or not.

Battery drain


Remove the fuse for radio. The tape player should stop clicking. Then try to see if the battery dies.

Car battery goes dead within 3 days it is my new pioneer radio that drains it.


Would not think so, radios do not use that much power. My car sits idle for weeks, still with power to constant 12v. Check your battery, IF going flat that quick, probably needs replacing

you need a draw test done on the car to start to diagnois the problem.it can take a few days to find the problem and should be done by a tech that knows how to check for electrical draws as its not an easy job to do and if you don`t know how to do this you may not find the problem or may jump to the wrong conclusion.

Light on dash reads "check


nancycmixon, When you see this "check your charging system" you need to have the alternator checked. This is the main component for the charging system. A normal alternator will put out 13.6 to 14.6 volts. A few tenths of a volt either way won't mean too much but if they are extremely over or under these values means you have a bad alternator. I believe that your vehicle has a voltage meter in the dashboard and it will usually read in the thirteen to fourteen volts range. As far as your battery losing its charge overnight means that you have another problem and that is you have what is called a parasitic drain. There are a certain amount of parasitic drains already in the car with the radio memory and maybe a clock that constantly displays the time and the antitheft system in the car. These will not drain your battery overnight. You have something else draining your battery that is your problem. Have the alternator checked and mention the battery drain. There is test for this but it is too lengthy to post here. Sorry about that. Good luck with this.

BATTERY CONSTANTLY BEING DRAINED DOWN. VEHICLE


i,personally, have NEVER heard of an AUDI defect that cannot be rectified.(are you sure your not buying shares in that dealer.....)take it to a VW dealer (who has the same diagnostic computer)and get a written diagnostics done,then you can see what needs to be done.then decide if its something you can do or they can fix for you...if problem persists,contact AUDI main importers,then AUDI in Germany,they will be very helpfull.

Pull fuse to locks and see if that solves the problem first, does the battery drain over night, could be a bad voltage regulator in alternator.
